Question about aftermarket fuel pump

2435 Views 12 Replies 2 Participants Last post by  ccarcher72
I recently purchased this Fuel Pump for Honda VT700C Shadow 750 VT750C 700 | eBay fuel pump from felcoproducts because it was a cheaper route to go. I also jumped the fuel pump relay because I thought it was bad.
The only time I can hear it run is when I turn the key. I'm having a problem with the bike cutting out and I think it is because the pump is not keeping the carbs full. Anyone else use one of these and did you have any issues with them?

I will have to check the plugs when it happens. I can feel the pump click every few seconds, so I think the pump is working. What am I looking for on the plug?

I should mention it is a pain in the ass to get started again when it stalls at operating temp too.
I checked them, and they are black. They were recently bought plugs too. So, its getting too much fuel in the cylinder?
When I attempt to restart right after it stalls, it will pop and backfire too.
The plugs are a cross between sooty and oily. I tried taking it out again and barely made it to 2nd. and it just wants to bog down. More throttle makes it worse until I pull in the clutch then it dies and won't start.

Another thing to mention: The mixture screw caps are gone indicating PO has done some adjusting of their own. The bike has been sitting since 06...will setting them back to factory preset and go from there solve this issue maybe?
Well, its been sitting for 8 years and it only had 8,083 original miles on it for an 85, so I jumped on it. Fuel pump was an issue. And had to clean carb a few times and noticed the idle jet kept plugging up. New fuel lines, new filter, cleaned tanks etc. New plugs, checked coils, pickup coils and plug wires....those all checked out good. Maybe the main jet needs extra cleaning too, not sure. Don't have a float level gauge, so not sure how to measure it.
This might be a stupid question, but concerning the fuel pump I bought and installed...Are they able to be installed upside down and still work properly? There is not a lot of space to work with putting this pump in considering I had to put a splice between the 3/8 and 1/4 inch hoses. I noticed the pump is getting hot too. The bike will run for a few minutes then stall. I turn the key off for about 10-15 seconds, turn key back on and the fuel pump runs until I assume the bowls fill then it will start.
It was the fuel pump not running consistently. Wasn't keeping the bowls full. This Monday went for my first real ride. Had to reach down while riding and tap the pump when bike started to stall and it would pi k back up. On the return ride home it ran perfectly, no stalling or anything. Cruising down the road in overdrive was awesome! Hopefully will have at least one more day of warmer weather to ride, then get it ready for some work over the winter.
